I like the original Bauhaus style (visited the Bauhaus twice) and I really like that one. It's sleek and modern, but it's also a pleasant place to be in for humans with some cool details, too. I think their style was bastardized into architectural wankery and, even more often, just building a simple box as cheaply as possible.
Le Corbusier is another early modernist that I see as more problematic than Bauhaus. He seems to have been a kind of champagne commie who wanted to build efficient but pleasant housing for the masses (not necessarily for people like himself). His ideas were put into use without testing and the results were whole city quarters incompatible with human life.
